Compliant mechanisms' design aims to create a larger workspace and simple structural shapes because these mechanical systems usually have small dimensions, reduced friction, less bending. From that request, we designed optimal bridge-type compliant mechanism flexure hinges with high magnification ratio, low stress by using joint, especially no friction This joint was dimensions for the studied method of grey relational analysis (GRA), which is based on Taguchi (TM), finite element (FEA). Grey grade (GRG) has been estimated an artificial neural network (ANN). The values were in good agreement predicted value regression analysis. analysis, signal-to-noise surface plot, variance demonstrated significantly affected equivalent displacement. displacement also verified experiment. outcomes deviation lower than 6%. Specifically, amplification ratio obtained as 65.36 times compared initial design.
